President Obama presented his plans for changing the country's health care system to the nation's doctors Monday.

He spoke before the American Medical Association in his hometown of Chicago.

The president said health care costs could be kept down by forming a government-run insurance plan that would compete with private insurance.

"If we do not fix our health care system, America may go the way of General Motors -- paying more, getting less, and going broke," Obama said.

But doctors are concerned the not-for-profit plan will drive private insurers out of business and then there is the opposition to more government control.

"Americans want lower costs and they want the freedom to choose their own doctors and their own care." said minority leader Sen. Mitch McConnell. "What they don't want is a Washington takeover of health care."

The president said for the first time publicly that health care reform would cost about $1 trillion over ten years.
